The plane accident that killed four people in a Connecticut neighborhood was not the first crash for the pilot, a former Microsoft executive who was taking his teenage son on a tour of East Coast colleges.

The pilot, Bill Henningsgaard, was presumed killed along with his son, Maxwell, and two children who were inside a house struck by the small propeller-driven plane on Friday. Four bodies were recovered from the wreckage and sent to the Connecticut medical examiner’s office on Saturday for identification, officials said.

Henningsgaard, a highly regarded philanthropist, was flying a small plane to Seattle in 2009 with his mother when the engine quit. He crash-landed on Washington’s Columbia River.

“I forced myself to confront that fact that the situation any pilot fears — a mid-air emergency, was happening right then, with my mother in the plane,” he wrote in a blog post days later.

In the Connecticut crash, Henningsgaard was coming in for a landing at Tweed New Haven Airport in rainy weather just before noon when the plane struck two small homes, engulfing them in flames. The aircraft’s left wing lodged in one house and its right wing in the other, with its tail section coming to rest upside down.

Two children, ages 1 and 13, have been missing since the plane crashed into their home. As their mother yelled for help from the front lawn, several people in the working-class neighborhood raced to rescue the children, but they were forced to turn back by the fire.

Authorities said previously that as many as six people could have died in the crash, but East Haven Deputy Fire Chief Anthony Moscato said the four recovered late Friday are believed to be the only victims. On Saturday, crews removed charred sections of the plane as National Transportation Safety Board investigators worked to determine the cause of the crash.

The pilot’s family learned it was Bill Henningsgaard’s plane through the tail number, said his brother, Blair Henninsgaard, the city attorney in Astoria, Ore.

In 2009, Bill Henningsgaard was flying from Astoria, Ore., with his 84-year-old mother to watch his daughter in a high school play when he crashed into the river as he tried to glide back to the airport. He and his mother, a former Astoria mayor, climbed out on a wing and were rescued.

Henningsgaard was a member of Seattle-based Social Venture Partners, a foundation that helps build up communities. The foundation extended its condolences to his wife and two daughters.

“There are hundreds of people that have a story about Bill — when he went the extra mile, when he knew just the right thing to say, how he would never give up. He was truly all-in for this community, heart, mind and soul,” the foundation wrote Friday in a post on its website.

Paul Shoemaker of Social Venture Partners told the Seattle Times that Henningsgaard was “an incredibly good, real, honest man, for the community, for his family, for this world.”

“The guy has already done so much for the world. And he was going to do so much more,” he said.

The 10-seater plane, a Rockwell International Turbo Commander 690B, flew out of Teterboro Airport in New Jersey and crashed at 11:25 a.m., the Federal Aviation Administration said. Neighbors reported they did not near any engine noise immediately before the crash.

Tweed’s airport manager, Lori Hoffman-Soares, said the pilot had been in communication with air traffic control and hadn’t issued any distress calls.

“All we know is that it missed the approach and continued on,” she said.
